Remember the movie National Lampoon’s Vegas Vacation, when gambling fever consumes Chevy Chase’s character, Clark W. Griswold? He goes on a losing streak to beat all losing streaks while his son, Rusty, wins four cars by playing the slot machines. Maybe Clark would have done better if he had read Probability For Dummies! In this article, you discover the basic ideas behind slot machines and how they work, so that you can get past the myths and develop a strategy based on sound probability.
Understanding average payout
- Generally, the more cash you put into a slot machine, the higher its payout percentage is going to be. The slots that require at least $1 pay out 95-99%, where 25 and 50 cent slot machines pay out less, 92-95%. Now for the sake of comparison, let’s say a certain slot machine has an RTP of 92% and it costs you $1 to spin its reels.
- On some slots, the coin value is set at a predetermined amount, but on the majority of modern online slots, you will find that you can select the value of your coin from the smallest amounts (usually around the £0.01 to £0.05 mark) up to the larger amounts (which can be anything from £0.50 up to £10 or even more on some high roller slots).
- Jackpot 6000 is a thrilling classic slot machine from NetEnt with a real old-school vibe. You can play with up to 5 paylines active, betting between 1 and 10 coins per spin. It is highly recommended to play with the maximum bet of 10 coins however, as this creates the possibility of triggering Supermeter mode.
Three-reel games – These are basic slot versions that have three vertical reels and then typically anywhere from one to five pay lines. Each pay line requires an individual wager, and maximum bet per line is three. So, five lines at the max bet would require a 15 credit investment for each round.
When casinos advertise that their slot machines pay out an average of 90 percent, the fine print they don’t want you to read says that you lose 10 cents from each dollar you put into the machines in the long term. (In probability terms, this advertisement means that your expected winnings are minus 10 cents on every dollar you spend every time the money goes through the machines.)
Suppose you start with $100 and bet a dollar at a time, for example. After inserting all $100 into the slot, 100 pulls later you’ll end up on average with $90, because you lose 10 percent of your money. If you run the $90 back through the machine, you’ll end up with 90 percent of it back, which is 0.90 x 90 = $81. If you run that amount through in 81 pulls, you’ll have $72.90 afterward (0.90 x 81 = 72.90). If you keep going for 44 rounds, on average, the money will be gone, unless you have the luck of Rusty Griswold!
How many pulls on the machine does your $100 give you at this rate? Each time you have less money to run through the machine, so you have fewer pulls left. If you insert $1 at a time, you can expect 972 total pulls in the long term with these average payouts (that’s the total pulls in 44 rounds). But keep in mind that casinos are designing slot machines to go faster and faster between spins. Some are even doing away with the handles and tokens by using digital readouts on gaming cards that you put into the machines. The faster machines can play up to 25 spins per hour, and 972 spins divided by 25 spins per minute is 38.88 minutes. You don’t have a very long time to enjoy your $100 before it’s gone!
The worst part? Casinos often advertise that their “average payouts” are even as high as 95 percent. But beware: That number applies only to certain machines, and the casinos don’t rush to tell you which ones. You really need to read or ask about the fine print before playing. You can also try to check the information on the machine to see if it lists its payouts. (Don’t expect this information to be front and center.)
Implementing a simple strategy for slots
Advice varies regarding whether you should play nickel, quarter, or dollar slot machines and whether you should max out the number of coins you bet or not (you usually get to choose between one and five coins to bet on a standard slot machine). In this section, you’ll find a few tips for getting the most bang for your buck (or nickel) when playing slot machines.
Basically, when it comes to slot machines, strategy boils down to this: Know the rules, your probability of winning, and the expected payouts; dispel any myths; and quit while you’re ahead. If you win $100, cash out $50 and play with the rest, for example. After you lose a certain amount (determined by you in advance), don’t hesitate to quit. Go to the all-you-can-eat buffet and try your luck with the casino food; odds are it’s pretty good!
Choosing among nickel, quarter, and dollar machines
The machines that have the higher denominations usually give the best payouts. So, between the nickel and quarter slots, for example, the quarter slots generally give better payouts. However, you run the risk of getting in way over your head in a hurry, so don’t bet more than you can afford to lose. The bottom line: Always choose a level that you have fun playing at and that allows you to play for your full set time limit.
Deciding how many coins to play at a time
When deciding on the number of coins you should play per spin, keep in mind that more is sometimes better. If the slot machine gives you more than two times the payout when you put in two times the number of coins, for example, you should max it out instead of playing single coins because you increase your chances of winning a bigger pot, and the expected value is higher. If the machine just gives you k times the payout for k coins, it doesn’t matter if you use the maximum number of coins. You may as well play one at a time until you can make some money and leave so your money lasts a little longer.
For example, say a quarter machine pays 10 credits for the outcome 777 when you play only a single quarter, but if you play two quarters, it gives you 25 credits for the same outcome. And if you play the maximum number of quarters (say, four), a 777 results in 1,000 credits. You can see that playing four quarters at a time gives you a better chance of winning a bigger pot in the long run (if you win, that is) compared to playing a single quarter at a time for four consecutive tries.
The latest slot machine sweeping the nation is the so-called “penny slot machine.” Although it professes to require only a penny for a spin, you get this rate only if you want to bet one penny at a time. The machines entice you to bet way more than one penny at a time; in fact, on some machines, you can bet more than 1,000 coins (called lines) on each spin — $10 a shot here, folks. Because these machines take any denomination of paper bill, as well as credit cards, your money can go faster on penny machines than on dollar machines because you can quickly lose track of your spendings. Pinching pennies may not be worth it after all!
Slot machines are the most popular game in any casino. Sure, people bet more on the lottery, and the worldwide sports betting market is huge. But slot machines are the game du jour in most casinos, especially in the United States.
Sadly, slot machines games also offer the worst odds in the casino except maybe for keno. The compounding effect of making hundreds of bets per hour at the slots make these games a bigger moneymaker for the casino than keno.
There’s no science to playing slots. You put your money in, spin the reels, and hope for the best. The only decisions you make are which game to play and how much to bet.
This post covers how much you should bet. You’ll often hear so-called gambling experts say you should always place the maximum bet on slot machines.
This isn’t true for most games.
There Are Two Kinds of Max Bets on Slot Games
You’ll only find one “Max Bet” button on a slot machine game, but some games allow you to adjust the number of paylines you bet on. These are older games. They preceded the guaranteed “243 ways to win” games.
The first time I saw one of these games, a friend of mine called them “penny slots.”
The minimum bet was 10 cents per payline and the game had 25 paylines. The minimum bet was, to my way of thinking, $2.50. You could never bet just a penny on that “penny slot” game.
Best Way To Bet On Slot Machines
The maximum bet was $1 per payline. This was a sneaky way of getting the players to lay down more money. If you hit “Max Bet” on that machine, it took $25 in credits from your balance.
The More Complicated the Slot Game, the Less Likely You’ll Win
If you don’t understand how much you’re betting when you push a button on a slot game, there’s something wrong with the game. Perhaps the gaming industry just went through a phase of bad design.
But just because a slot machine game has multiple paylines, you shouldn’t assume that you’ll lose money if you bet on fewer paylines. Each bet on each payline is a separate bet, so playing all the paylines at once might make you more likely to see a winner. But you’ll also see more losing spins on the other paylines to compensate (in the long run, anyway).
The game is still programmed to spin as if all the paylines are active. I watched in horror, as that $25 bet spun the reels. I got lucky and the machine paid a low prize. I didn’t lose $25.
You can save money on a slot machine like this in two ways.
- You can bet on fewer paylines.
- You can lower the size of your bet.
My buddy disabled all the paylines and played $1. We saw a big prize combination come up but it didn’t pay anything. It was on a deactivated payline. There was no pattern on the one active payline.
A Few Older Games Increased Your Probability With Your Bet Size
This kind of game worked in the opposite way. You didn’t disable or enable paylines. The game’s help screen said some features were only enabled for the max bet.
We deduced that meant the theoretical return to player was calculated only for the max bet. And if the game wasn’t allowing you to use all the features with lesser bets then it must have had a lower RTP.
I went back to play some blackjack that night but my friend stayed and played that game. He did okay, not great. He said it made a big difference to play the max bet.
A Basic Slot Game Doesn’t Change the Probabilities
Whether it’s a 3D video slot with monsters running around the screen or just a classic three-reel game, if the slot game doesn’t disable paylines or require max bets, then the probabilities don’t change.
You can bet the minimum or maximum credits, and it won’t affect the outcome of the game. You simply change the number of guaranteed spins you can play.
If you have $300 and a game has a $1 minimum, you can play that game 300 times. If you make a maximum bet of $5 on every spin, then you can only play the game a maximum of 60 times (if you lose every time).
This makes a difference to some players. Other players say you’re not going to lose 60 times in a row, so why worry about that? Bet the max and get the most from your prize.
Most Progressive Slot Games Only Pay on Max Bets
If you’re playing a progressive slot game, then you need to make a maximum bet. I’ve seen a few games with multiple progressive jackpots where you only needed a max bet for the biggest jackpot.
If you have two versions of the same slot game, one is progressive and the other is not, you might as well play the max bet on the progressive version of the game.
Progressive slot games have a mixed reputation. I’ve talked to people who refuse to play them. They’re convinced the payouts are less on progressive games.
And I know people who almost exclusively play progressive slot games. They would rather win a big prize beyond whatever the machine itself pays. They don’t have to win $1 million if they can come away with a few thousand.
I’ve seen it play out both ways. I’ve never been in a casino where someone won more than $10,000.
The Math Says Max Bets Put You Ahead Faster
Assuming you find a slot machine that pays reasonably well, maybe it’s on a “hot” streak despite its regular RTP, why not play only max bets?
If the maximum payout is 1000x your bet, you’ll make $999 on a $1 bet or $4995 on a $5 bet. That’s a really simple equation, so why doesn’t everyone bet that way?
If you’re down to your last $20, you may decide to “roll it up. ” But what’s the difference between rolling up $20 and rolling up $200?
It comes down to how many spins you can guarantee yourself. This is a psychological game we play with ourselves. The odds of winning on the next spin are the same regardless of how much you bet.
There Is Another Advantage to Not Making Max Bets
If you want to play a lot of different games and you don’t have an unlimited bankroll, then playing minimum bets allows you to spread your time around.
Some players like to test the games when they visit a casino for the first time. They make a decision based on luck.
I remember watching a man approach a slot machine late one night. I was getting ready to leave. He put a dollar in the machine and spun the wheels.
He went down the line of machines until one of them paid. There, he stopped and began playing.

Conclusion
Slot game designs have become more polished, but their rules are less confusing. People want to push a button and win some money.
I think caution is only warranted if you’re unfamiliar with the games and you don’t know immediately if they have any special rules. It’s always a good idea to read the pay tables first.
And if you’re a little confused by the game rules, then only play minimum bets until you understand what the game is doing.
There’s no need to rush into max bets if you’re not ready to take that chance.
